SILO DOOR.

Application filed May 18,

To all 'to 710m t'mufz/ concern Be it known that I, JAMES H. PnAnsoN, a citizen of the United 'Stzites, residing at Bloomiield, in the county ot Greene and State oit indiana, have inventedanew and useful Silo Door, ot' which the following` is a speciiication.

it is the object of this invention to provide a novel means for mounting a door on a silo.

1t is within the province of the disclosure to improve generally and to enhance the utility of devices of that type to which the invention appertains.

YWith the above and other objects in view, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details. ot construction hereinafter described and claimed, it being; understood that, within the scope ot what is claimed, changes in the precise embodiment of the invention shown can be made without departingfrom the spirit of the. invention.

ln the accompanying' drawinirs:-

Figure 1 shows in front elevation, a portion of a silo, whereunto the device torming' the subject matter of this application has been applied; Figure 2 is a. vertical section taken through a port-ion of a silo equipped with the device hereinafter described and claimed, the door being closed; Figure 3 is a vertical section taken through `a portion of a silo equipped with the device hereinafter described and claimed, the door being' open; Figure 1 is an elevation showing' the relations existing between. sundry parts when the door is open; and Figure 5 is a 't'ragmental perspective disclosing' the interengaging elements on the suspension members and on the bearings.

The numeral 1 marks part of a. silo having a. doorway 2 provided with an edge recess 3. Bearings 1 are located above the 'doorway 2 and are secured as indicated at 5 .to the silo 1. The adjacent vertical inner faces of the bearings 1 are provided with notches 6. A pivot rod '7 is mounted in the bearings 1. from moving endwise by a head 8 on one end of the rod, engaging one of the bearings 4t and by a nut on the other end of the rod, engaging` the other of the bearings and designated by the numeral 9.

A pair of suspension members 10 is pro- The pivot rod is prevented- 1920. Serial No. 382,232.

vided. The suspension members 10 have curved upper ends 11 disposed between the bearings TJ: in contact therewith, the said ends beingl mounted to swing on the rod 7 The ends 11 of the suspension members 1() have lugs 12 adapted toV be engaged in the 'notches o of the bearings et. The curved ends 11 of the suspension members 10 are resilient, so that the lugs 12 can spring into and out of the notches 6. intermediate their ends, the suspension members 10 are connected by a rod 111. The lower ends of the suspension members 10 are connected by a rod 15 mounted to turn in bearings 16 secured as indicated at 17 to a door 18 adapted to cooperate with the doorway 2 and provided with a flange 19 adapted to be received in the recess 3, The rod 15 has a head 20 on one end and a nut 21 on the other end, the head and the nut cooperating with the respective bearings 16 to prevent the rod from moving endwise. Any suitable means may be provided for holding the door 18 positively in a closed position. It desired, a button 22 may be united to the door 18 by a pivot element 23 for the purpose last above alluded to.

he door 18 maybe swung' inwardly and upwardlv within the silo 1 as shown in fig'- ure 3 leaving` the doorway 3 practically unencumbered. rlhe suspension members 10 are provided with curved ends 11 for two purposes: iirst, to receive the wall of the silo 1I at the upper edge of the doorway-2, when the door 18 is swungupwardly and inwardly as shown in Figure 3; and, secondly, to space the rod 14C tar enough from the outer surface ot the silo 1, when the door is closed, as shown in Figure 2, so that the said rod may serve as one rung ot a ladder. Vhen the door 18 is swung into an open position as shown in Figure 3, the lugs 12 on the ends 11 of the suspension members 10 enter the notches 6 and hold the door 18 in an open position. Vhen, however, the door 18 is closed, the lugs 12 ride out of the notches 6 on the inner surfaces of the bearings, the ends 11 of the suspension members springing' inwardly as shown in Figure 1. I

Having' thus described the invention, what is claimed is 1n a device oit the class described. a building having; a door way; a door for the door Way; bearings on the building; a rst rod CIT extended between the bearings; sulliporting members eaeli having` a curved resilient end, the said resilient ends of the supporting members and the bearings havin;` intereng'aging '.eleinentswhioh eoaet to hold the door in an open position, the supporting` members being Connected pivotally with the door, the said ends of the supporting members being mounted pivotally` on the rod to permit the door to open and to close, and

beingslidable on the rod, longitudinally thereof, to permit said interengaging elements to move into and out of cooperating relation; a second rod connecting` the supporting members, and located Closely adjar oent to thesaid resilient ends ol the supportingI members and closely adjacent to the lirst rod, but outwardly `thereof whereby the second rod Will tend to stiften the said ends of the supporting members and to enhance the hold of the interengaging elements upon each other, and whereby, when pressure is exerted upon the second rod, the pressure will have an appreciable component tending to open the door, should the door be stuck.

` In testimony that I claim the foregoing as own, I have hereto aiiixed my signature in the presence of two Witnesses.

`JAMES H. PEARSON.
